Cannot impliciily convert type double to NinjaScript Series,double

[Richard168]

I'm trying to add an SMA average volume to the volume indicator.


AddPlot(Brushes.Blue, "Avg"); // NEW -- Average Volume Plot [0]
...
double avgVol = SMA(Volume, Period)[0];
Values[0] = avgVol;
..
[Browsable(false)]
[XmlIgnore()]
public Series<double> Default
{
get { return Values[0]; }
}
...
But I got the following compile error:



Error: Cannot impliciily convert type double to NinjaScript Series,double>

Code: CS0029

I have the same problem when I changed to:

Values[0] = SMA(Volume, Period)[0];

However, I was succesful in compiling the following code when I did in another NinjaScript:
...
DiffUp[0] = CCI(Period)[0];
...
DiffDown[0] = CCI(Period)[0];

...

I could find much information on the Beta 8 Help Guide. Appreciate any suggestions you can provide.

Thanks,

Richard

double avgVol = SMA(Volume, Period)[0];
Values[0] = avgVol;

Values[0][0] = avgVol;

[Richard168]

Values[0][0] = avgVol;

Thanks for your quick reply. It works!

Hello Richard168,

Thanks for your posts and thanks to member -=Edge=- for his appreciated input.

I found that when adding the sma plot to the indicator that I had to set it to be Values[1][0] as this was the 2nd plot (the Vol is the first plot [0][0]).

Alternatively you don't need to create an indicator to accomplish this. You can add the SMA to the Vol indicator on the chart by changing the input series via the indicator panel of the SMA indicator to be the Vol indicator. This method allows you to use any moving average and can be done without coding. See attached.
